(a) Forelimb
(b) Skull
(c) Scapula
(d) Pelvic girdle
Show Answer & Explanation
Answer: (c) Scapula
Explanation:
1. The coracoid process is a projection of the scapula.

(a) 6 pairs
(b) 5 pairs
(c) 3 pairs
(d) 2 pairs
Show Answer & Explanation
Answer: (d) 2 pairs
Explanation:
1. There are 12 pairs of ribs.
2. The last two pairs (11th and 12th) are not attached ventrally and are called floating ribs.

(a) Atlas
(b) Coracoid and frontal
(c) Pterygoid and frontal
(d) Aretynoid and pariental
Show Answer & Explanation
Answer: (c) Pterygoid and frontal
Explanation:
1. The pterygoid (a process of the sphenoid) and frontal are skull bones.
2. Atlas is a vertebra, coracoid is a process of the scapula and arytenoid is a laryngeal cartilage.
Teacher's Note:
1. Only option (c) lists skull bones.
(a) Both (A) and (R) are true but (R) is the correct explanation of (A)
(b) Both (A) and (R) are true but (R) is not the cor- rect explanation of (A)
(c) (A) is true statement but (R) is false.
(d) Both (A) and (R) are false
Show Answer & Explanation
Answer: (c) (A) is true statement but (R) is false.
Explanation:
1. Assertion is true because the knee is a hinge joint.
2. The reason is false because the knee joint is formed by the femur, tibia and patella, and the fibula does not take part.
Teacher's Note:
1. So (A) is true and (R) is false.
(a) Muscle contraction
(b) Nervous contraction
(c) Tissue regeneration
(d) All the above
Show Answer & Explanation
Answer: (a) Muscle contraction
Explanation:
1. Cross bridges between actin and myosin are formed during muscle contraction.
2. The myosin head binds to the active site on actin and pulls the thin filament.
Teacher's Note:
1. This is the basis of the sliding filament theory.
(a) Muscle fibres
(b) Nerve fibres
(c) Axon
(d) Dendron
Show Answer & Explanation
Answer: (a) Muscle fibres
Explanation:
1. Purkinje fibres are modified cardiac muscle fibres in the ventricular walls.
2. They carry the impulse rapidly to all parts of the ventricles.
Teacher's Note:
1. They are not nerve fibres.
(a) Group of specilised muscle fibres
(b) Cartilage in node of heart
(c) Connective tissue node
(d) None
Show Answer & Explanation
Answer: (a) Group of specilised muscle fibres
Explanation:
1. The SA node is a group of specialised cardiac muscle fibres in the right atrium wall.
2. It acts as the pacemaker of the heart.
Teacher's Note:
1. It starts the impulse for each heartbeat.
(a) H line
(b) Sarcomere
(c) H zone
(d) None
Show Answer & Explanation
Answer: (b) Sarcomere
Explanation:
1. The sarcomere, the part of the myofibril between two Z lines, is the functional unit of contraction.
2. The H zone is only a part of it.
Teacher's Note:
1. Sarcomere is the answer.
(a) Dark colour
(b) Melanin colour
(c) Black colour
(d) Double refractive index
Show Answer & Explanation
Answer: (d) Double refractive index
Explanation:
1. The A band is dark because the thick myosin filaments are anisotropic, meaning they have a double refractive index for polarised light.
2. The I band is isotropic.
Teacher's Note:
1. These names give the bands their appearance.
(a) Heart
(b) Eye lids
(c) Arm
(d) Jaws
Show Answer & Explanation
Answer: (b) Eye lids
Explanation:
1. Eyelid muscles show the fastest contraction, as in blinking.
2. Skeletal muscles in the jaw and arm contract more slowly.
Teacher's Note:
1. The heart contracts rhythmically at a slower rate.
(a) Intestine
(b) Stomach
(c) Uterus (Pregnant)
(d) Urinary bladder
Show Answer & Explanation
Answer: (c) Uterus (Pregnant)
Explanation:
1. The smooth muscle of the pregnant uterus has the longest fibres, as the fibres lengthen greatly during pregnancy.
2. Intestinal fibres are much shorter.
Teacher's Note:
1. Learn this as a fact.
(a) Ectoderm
(b) Mesoderm
(c) Endoderm
(d) All of above
Show Answer & Explanation
Answer: (a) Ectoderm
Explanation:
1. The muscles of the iris and ciliary body develop from ectoderm, which is an exception.
2. Most muscles are mesodermal.
Teacher's Note:
1. The myoepithelial cells of sweat glands are also ectodermal.
(a) Actin
(b) Myosin
(c) Sarcomere
(d) Actomyosin
Show Answer & Explanation
Answer: (c) Sarcomere
Explanation:
1. The sarcomere is the basic contractile unit between two Z lines.
2. Actin and myosin are only the proteins within it.
Teacher's Note:
1. Actomyosin is the complex formed during contraction.
(a) Hansen
(b) Huxley
(c) Bohr
(d) Huxley, Huxlay & Hensen
Show Answer & Explanation
Answer: (d) Huxley, Huxlay & Hensen
Explanation:
1. The sliding filament theory was proposed by Huxley and Niedergerke and by Huxley and Hanson in 1954.
2. Hence all the names in option (d) are associated with it.
Teacher's Note:
1. It is the accepted mechanism of contraction.
(a) G-actin
(b) Actin
(c) Tropomyosin
(d) Troponin
Show Answer & Explanation
Answer: (d) Troponin
Explanation:
1. In the resting state, troponin on the thin filament masks the active sites for myosin on the actin filament.
2. Calcium binding to troponin removes this block.
Teacher's Note:
1. Then cross bridges can form.
(a) Starch
(b) Glycogen
(c) Lactic acid
(d) Pyruvic acid
Show Answer & Explanation
Answer: (c) Lactic acid
Explanation:
1. During strenuous exercise oxygen supply falls and anaerobic breakdown of glucose gives lactic acid.
2. Pyruvic acid is converted to lactic acid.
Teacher's Note:
1. Lactic acid accumulation causes fatigue.
